I know that when making a call for the openrouteservice directions api, you can set the radius (or snapping tolerance). I am now using the optimization api and I regularly get the error that says “Could not find point x within 350.0 metres”.
I gather that 350 metres is the default for optimization. Now I wonder if there is a way to set the radius variable to a different value somehow for this api as well?
No, sorry, not possible.
However, that should only be the final route which it can’t process, since matrix calls don’t throw errors. So don’t use the g option, and call ORS yourself for final vehicle routes, using bigger radii and the start/end & job locations.
